'Outlander' Star Caitriona Balfe Is Engaged -- See Her Ring!

The Outlander star is engaged to her boyfriend of two years, Tony McGill -- and debuted her stunning ring on the Golden Globes red carpet on Sunday.

“It happened over the break," Balfe told Peopleahead of the awards show, where she was nominated for Best Actress in a Television Series, Drama. "I’m very happy."

The 38-year-old actress, who has kept her relationship with McGill out of the public eye since they were first spotted together in 2015, certainly wasn't shy about showing off her engagement ring.

And while she didn't hit the red carpet with her new fiance, her onscreen husband, Sam Heughan, has been by her side throughout much of awards season.

“He’s the sweetest. I’m so lucky,” she gushed to ET on the Golden Globes red carpet. “I have an incredible job that I love, but I get to go to work with one of my best friends. We are just so grateful and we have the best fans and so many of them are here and they’re so loud and fantastic.”
